Custom Cables for EVGA G2 Power Supply.. what of capacitors?

post #1 of 3
Thread Starter 
So years ago, my first and only true attempt at cable sleeving happened and it came out.. decent. [image]

But recently I've been making strides towards getting a new GPU, and have as a result been making a couple of 8 Pin cables; which look far better in terms of quality than my original sleeves cable-job. But it got me thinking about the cables, and an idea hit me that I'm not sure would work or not.. I'm looking for opinions on it. The idea is essentially making a "converter" cable, maybe an inch or two in length, that plugs into the power supply VGA port. The EVGA G2 pins aren't 1:1 so there's a lot of crossover and double wires; which doesn't look pretty. This "converter" would make all the crossovers and double wires right at the power supply, behind a PSU shroud, unseen. Then a longer cable, actually sleeved, could have a 1:1 pinout which would plug right into the converter and into the GPU respectively; the converter is essentially the middleman between the actually sleeved wire and the power supply. Of course there are also capacitors on some of the EVGA wires.. so my hope would be to move those ugly capacitors (which normally come right out of the connector that plugs into the GPU and isn't a pretty sight either) to the converter instead.

My question is would this work? Assuming the pinning was correct, could a "converter" for the cables work, even with capacitors and double wires? Would performance be dampened by not having the capacitors right near the GPU connector itself?

Thanks!

You could definitely make some short cables, that's what http://www.ensourced.net/corsair-sf-series-shortys/Joey at Ensourced does. You could add the capacitors, it wouldn't hurt at all, but it might make it much harder to make the converters, as the capacitor takes up a lot of room. The farther back a capacitor on a wire from the load, the less efficient it is at filtering ripple (that's why the capacitors are so close.) The reason is the actual wire will act as an inductor the farther back the capacitor is on the wire.

Anyways, either way you go, you should be fine. I've seen plenty of people w/o caps on their EVGA PSUs, (I'm not using caps on my cables I'm building.) The ripple suppression is already so mythically good on the G2, even without caps, it should still be one of the better if not one of the best PSUs in ripple suppression still.

This is good to hear smile.gif am I.. hurting myself by including those capacitors on the converter, though? Or am I only standing to gain from it, if just a bit?
